SIM800L GPRS GSM Module Core Board Quad-band TTL Serial Port

GPRS multi-slot class12 connectivity: max. 85.6kbps(down-load/up-load) GPRS mobile station class B Controlled by AT Command (3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands) Supports Real Time Clock Supply voltage range 3.4V ~ 4.4V Supports A-GPS Supports 3.0V to 5.0V logic level Low power consumption, 1mA in sleep mode Compact size 23mm x 35mm x 5.6mm Micro SIM Card Product Description The Sim800L Module is a compact and budget-friendly GSM module powered by the SIM800L chipset from Simcom. It supports quad-band GSM and GPRS networks, making it suitable for global use. Perfect for projects where size and cost are key considerations, the Sim800L GSM module is an excellent choice for launching IoT initiatives. With this versatile module, you can even create your own mobile phone functionality. Using this module, you can: – Send Text Messages (SMS) Make or receive Phone calls. Connect to Internet via GPRS TCP/IP The main drawback of this module is works on 3.7 to 4.2 volts so you cannot power it directly through Arduino or Raspberry Pi. Moreover, the sim800L GSM and GPRS module requires upto 2 ampere current so accordingly design your power supply. You can use a 3.7-volt lipo battery to directly power the GSM module. You can communicate with SIM800l module via UART port, supports command including 3GPP TS 27.007, 27.005 and SIM COM enhanced AT Commands. Features Quad-band 850/900/1800/1900MHz – connect onto any global GSM network with any 2G SIM (in the USA, T-Mobile is suggested). Make and receive voice calls using a headset or an external 8Ω speaker and electret microphone. PWM/Buzzer vibration motor control AT command interface with "auto baud" detection Send and receive SMS messages. Send and receive GPRS data (TCP/IP, HTTP, etc.). Scan and receive FM radio broadcasts. Lead out buzzer and vibration motor control port. AT command interface with "auto baud" detection. Onboard IPEX socket that can be connected to external antenna. Breakouts for external 8W speaker and electret mic if you don't want to use a headphone. Level shifting circuitry so you can run it with 2.8V to 5V logic. Vibrational motor (buzzer) driver so you can have noiseless notifications. uFL or SMA connections for external antenna Indicator LEDs for power and network connectivity Standard SIM slides into the back Specification: Operating Voltage (VDC) 3.7 ~ 4.2 Peak Current (A) 2 Package Included 1 x SIM800L GPRS GSM Module 1 x Spring Antenna 2 x Pin headers
